I was recently on a boat dive when I saw something that shocked me. We had just arrived at the dive site and everyone started gearing up when I looked across to the other side of the boat in time to see an older gentleman donning his scuba unit a la Mike Nelson -- right over the head and onto the back. Although, it wasn't all that graceful. He struggled quite a bit and it scared the crap out of me and the DM, who expressed concern for the guy's safety (though no correction or anything like that). He was older and might have been a long-time diver for all I know, and so I guess I am wondering if this was ever considered an acceptable/appropriate way of getting into your scuba. I always thought that Mike did it more out of theatrics and, in any event, Mike's tanks were made of wood, which probably made it safer than what I witnessed with an aluminum 80. Was I seeing a bit of history or just a misguided Mike Nelson admirer?
